Bismuth tri-iodide (BiI3) is an attractive material for room temperature radiation detectors because of its wide bandgap energy and high photon stopping power. In this paper, BiI3 crystals have been grown by the vertical Bridgman technique using commercially available powder. The grown crystals have been characterized in terms of their structural properties and stoichiometry. Room temperature radiation detectors have been fabricated from the crystals and tested by measuring their leakage currents and spectral responses. A clear peak corresponding to 5.48 MeV α-particles (241Am) was recorded with an 82 μm thick BiI3 detector with palladium electrodes of 1 mm in diameter. The energy resolution of the 5.48 MeV peak was found to be 2.2 MeV FWHM.
